I think there’s still a bit of magenta noise on Cushing’s face.
This is not magenta noise. It is supposed to be present. Although the magenta was too apparent in earlier iterations, Peter Cushing had very thin skin, resulting in magenta blodges on his face, especially around the eyes:
I like this picture. The blodges are not so much magenta as reddish skin. It looks very natural in this image.
